[sparc] unable to link against optimized libpthread due to wrong symbols

[Fabio Massimo Di Nitto]

From David S. Miller.

[ Jeff, when people try to link 64-bit pthread applications on
  sparc on Niagara or UltraSPARC-III boxes, they get link errors
  because glibc doesn't set the symbol versions correctly in
  libpthread.so in these cases... ]

The bug here is an error in the regular expressions used
in linuxthreads/shlib-versions and nptl/shlib-versions

They both use "sparc64-.*-linux.*" but it should be using
"sparc64.*-.*-linux.*"

The other shlib-versions files in the glibc tree get this right.

the problem has been addressed in feisty with glibc (2.5-0ubuntu7) feisty; urgency=low
upload.

In attachment the testcase to reproduce the problem.

A Niagara machine or faure is required to reproduce the problem. The problem does NOT show up on non optimized glibc/CPU.
